Killer yeast strains can be a problem in commercial processing because they can kill desirable strains. The killer yeast system was first described in 1963. Study of killer toxins helped to better understand the secretion pathway of yeast, which is similar to those of more complex eukaryotes. I did some reading on ciders a while ago and it seems that saccharomycodes ludwigii is considered as spoilage yeast, and sweet ciders are especially prone to be infected by it. It is said to be sulphite resistant and to produce flaky deposit and diacetyl.

The yeast cultures were inoculated at a cell count of 1E6 CFU/ml after culturing them in YPD medium. In total, 4 different fermentations were carried out: 1) Saccharomycodes ludwigii in wort without hops (S. ludwigii w/o hops) P. Membranifaciens, P. Anomala, and candida spp are known for film formation on the surface of bulk wines in unfilled containers Yeast species regarded as the most dangerous to wines, ie, Dekkera/brettanomyces spp., Z. Bailii, and S. Ludwigii, are seldom detected in yeast studies performed in wineries. 27.

S. ludwigii and Z. rouxii are considered suitable yeasts to produce fermented beverages with a low‐alcohol content 12, 21 - 23 because of their total or partial inability to ferment maltose, which is the main fermentable sugar in wort, as indicated in Table 1 24, 25.

Ludwigii yeast

Saccharomycodes ludwigii, This strain of non-conventional brewing yeast has been found to be useful when brewing a low alcohol beer.

(Adjusting the pH of the wort is recommended.) Saccharomycodes ludwigii has become a commonly used yeast for the production of low-alcohol or alcohol-free beers in Germany and Italy (7,17,110, 111). It is a good example of the novel use of non S’codes ludwigii is a yeast commonly considered as a wine contaminant due to its high production of ethyl acetate, acetoin or acetaldehyde, with negative effects on the sensory profile at levels above its perception threshold. However, S. ludwigii was identified to be a worthwhile yeast species for low‐alcohol and alcohol‐free beer production. In particular, the beer produced using DBVPG 3010 showed the lowest ethanol content (0.5% v/v), an appreciable amount of esters (about 15 mg/L) and higher alcohols (about 28 mg/L), more than the other S. ludwigii strains examined in previous studies 12 , 22 . A symbiotic culture of bacteria and yeast that is used for fermenting sweet tea into kombucha. White Labs’ SCOBY is free of food pathogens and has been genetically identified to know specially what yeast and bacteria are involved in the fermentation of kombucha.

However, S. ludwigii was identified to be a worthwhile yeast species for low‐alcohol and alcohol‐free beer production.

Other yeast that were found to be present, but which were not quantitatively isolated included Brettanomyces/Dekkera, Saccharomycodes ludwigii, Pichia, Debaryomyces and Metschnikowia type species. In the vat house, the predominant yeast isolated outside of the fermentation season was Brettanomyces / Dekkera type species.

In this fermentation of the undiluted (100% (v/v)) pineapple juice, S’codes ludwigii plays a major role in the ethanolic fermentation and helps to prolong the viability of H. mentation, contains at least five yeast strains (Sac-charomycodes ludwigii, Saccharomyces cerevisiae, Saccharomyces bisporus, Torulopsis sp.
